Abstract
The utility model discloses a kind of test probe of automotive wire bundle measurement jig, relate to wire harness processing utility appliance field.Comprise contact needle and shank, wherein, contact needle is binodal, and the bottom saved under contact needle is fixedly connected with the upper end of shank, and the diameter of shank is greater than the diameter in joint portion under syringe needle; Shank lower end is also provided with inner chamber, is provided with spring in inner chamber, is connected the bottom of syringe in the measurement jig of place by this spring.Test probe of the present utility model is applicable to the test multiple diameter automotive wire bundle terminal different with the degree of depth, and test probe is fully contacted with automotive wire bundle terminal, and alternative strong, measuring accuracy is high, and can not make terminal, when testing, deformation occur.
Description
Technical field
the utility model relates to wire harness processing utility appliance field, is specifically related to a kind of test probe of automotive wire bundle measurement jig.
Background technology
In automotive wire bundle making work, sample testing is carried out to assembled automotive wire bundle and to be absolutely necessary a ring.Test is, is generally to access in measurement jig by wire harness, forms loop, and in supporting display device, shows relevant loop information.
Measurement jig is all provided with the probe corresponding with the terminal of the wire harness that need test, the termination contact of probe pin upper ends and wire harness, in the corresponding syringe of lower end built-in test tool, but existing probe is the probe of overall even thickness, this type of probe is due to the restriction of size and projecting height, only be applicable to the probe that the size of calibrating terminal and the degree of depth all adapt, if when even misapplying the automotive wire bundle terminal in MTD is relatively shallow, also easily cause this Wiring harness terminal inside that deformation occurs, and cause damage and affect measuring accuracy, this type of probe is made to have more limitation, alternative is not strong.
Utility model content
The purpose of this utility model is for solving the problems of the technologies described above, and provides one fully can contact with automotive wire bundle terminal, alternative strong, the test probe of the automotive wire bundle measurement jig of not fragile Wiring harness terminal.
For achieving the above object, the technical solution of the utility model is:
A kind of test probe of automotive wire bundle measurement jig, comprise contact needle and shank, it is characterized in that: described contact needle is binodal, and the bottom saved under this contact needle is fixedly connected with the upper end of described shank, and the diameter of shank is greater than the diameter in joint portion under syringe needle; Described shank lower end is provided with inner chamber, is provided with spring in inner chamber, is connected the bottom of syringe in the measurement jig of place by this spring.
Described shank upper end is provided with groove, is provided with fore shaft in groove, and the bottom saved under described contact needle is provided with corresponding lock dog, by the two, syringe needle is fixed on shank upper end.
Described contact needle saves with the length of lower joint than being 2:1.
Test probe of the present utility model is applicable to the test multiple diameter automotive wire bundle terminal different with the degree of depth, and test probe is fully contacted with automotive wire bundle terminal, and alternative strong, measuring accuracy is high, and can not make terminal, when testing, deformation occur.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Illustrate: 1, contact needle 2, upper joint 3, lower joint 4, shank 5, spring.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
The test probe of automotive wire bundle measurement jig as shown in Figure 1, this test probe comprises contact needle (1) and shank (4) two parts.Shank (4) lower end is provided with inner chamber, linking springs (5) in inner chamber outwardly, shank (4) is placed in the syringe of corresponding measurement jig, and connect the bottom with syringe by this spring (5), when test probe upper end is stressed, the height of test probe can Flexible change, and by spring (5) buffering, to make at automotive wire bundle when testing, its terminal inner can not be out of shape because of the upper top of tested person probe.
The contact needle (1) of test probe is double-joint type, and namely the diameter of upper joint (2) is less than the diameter of lower joint (3), and on contact needle, the length of joint (2) is the twice of lower joint (3) length simultaneously.The bottom of contact probe is connected with the upper end of shank (4), and shank (4) diameter saves the diameter of (3) under being greater than contact needle, the upper end of shank (4) is provided with groove simultaneously, fore shaft is provided with in groove, lower joint (3) diameter of contact needle is identical with the diameter of above-mentioned groove, and its lower end is provided with corresponding lock dog, makes test probe be fixedly connected with shank (4).
Probe is installed on after in the sleeve of measurement jig, contact needle (1) will be exposed to the needle cylinder surface of measurement jig, stressed to when pressing down when the terminal of automotive wire bundle and probes touch, the upper joint (2) of contact needle (1) of test probe can be stretched into terminal inner sky portion and fully contact with terminal, to test the connection of wire harness; If when the comparatively dark and diameter of terminal inner is greater than the diameter of joint (3) under contact needle (1), saves (3) under contact needle (1) and also can stretch into terminal inner, make contact needle (1) fully contact with terminal, obtain accurate test data.
The above only have expressed preferred implementation of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion, improvement and substitute, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
Claims (3)
1. the test probe of an automotive wire bundle measurement jig, comprise contact needle (1) and shank (4), it is characterized in that: described contact needle (1) is binodal, the bottom saving (3) under this contact needle (1) is fixedly connected with the upper end of described shank (4), and the diameter of shank (4) saves the diameter in (3) portion under being greater than syringe needle; Described shank (4) lower end is provided with inner chamber, is provided with spring (5) in inner chamber, is connected the bottom of syringe in the measurement jig of place by this spring (5).
2. the test probe of a kind of automotive wire bundle measurement jig according to claim 1, it is characterized in that: described shank (4) upper end is provided with groove, fore shaft is provided with in groove, the bottom saving (3) under described contact needle (1) is provided with corresponding lock dog, by the two, syringe needle is fixed on shank (4) upper end.
3. the test probe of a kind of automotive wire bundle measurement jig according to claim 1, is characterized in that: described contact needle saving (2) with the length ratio of lower joint (3) is 2:1.
